The California newt is a small amphibian with a warty grey back and a bright orange-yellow belly. It lives only in California, in the western United States. Its skin contains a powerful poison, so it is a good example of an animal you should look at but never handle.1

Hasiera

California newts live in woodlands and chaparral near the small ponds and creeks where they breed. During the day they hide under rocks, logs or leaf litter. They travel to ponds, streams and slow-moving water to breed, especially during the wet season.1

Nola ezagutu

Warty, slate-grey skin on the back1
Bright orange-yellow skin on the underside1
Orange skin around the bottom of the eye (the rough-skinned newt has grey there)1
Eyes that stick out beyond the edge of the jaw when seen from above, giving the head a bullet-like shape1
Adults are about 13 to 20 cm long1

Askotan honekin nahasten da: The rough-skinned newt looks very similar and is often hard to tell apart in the field. The California newt has orange skin around the bottom of the eye and eyes that stick out past the jaw, while the rough-skinned newt has grey skin there and eyes that do not stick out. The red-bellied newt has dark irises instead of yellow, more red underneath, and a dark band across the vent.1

Pozoi-indarra

Pozoia azalean

Bere azala toxikoa da. Arriskutsua da ukitzea, miazkatzea edo jatea.

Zer egiten du bere toxinak?

This animal is poisonous, not venomous, so it does not bite or sting. Its skin glands release tetrodotoxin, a neurotoxin (a poison that attacks the nerves). It is hundreds of times more toxic than cyanide and is the same toxin found in pufferfish and harlequin frogs. It is strong enough to kill most vertebrates, including humans.1

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: Oso arriskutsuaTratamendurik jasotzen ez duen pertsona bat hil dezake.

The toxin is strong enough to kill people. Because of their toxin, California newts have very few natural predators.1

Zer egiten du beldurtzen denean?

When threatened, it performs the unken reflex: it stretches out, arches its body, and lifts its head and tail into the air to show its bright belly. It can also produce a foamy substance when exposed to high temperatures.1

Norbaitek ukitu edo jan badu

Norbaitek bat ukitu badu: garbitu eskuak ondo eta ez ukitu begiak edo ahoa. Haur edo maskota batek bat miazkatu edo jan badu: deitu zure intoxikazio-zentrora edo larrialdi-zenbakira.

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
Ukitu edo jan baduzu: ez igurtzi begiak edo ahoa, garbitu eskuak eta lortu mediku-laguntza.

Ez dabil zure atzetik. Pozoia ezerk jan ez dezan baino ez du. Seguru egoteari buruz gehiago

Datuak

Because snakes evolved resistance, newts have evolved to make far more toxin than any other predator could need, an evolutionary arms race.1

The foam the newt produces forms a protective layer that helps it keep moisture and shields it from burns during wildfires.1

Researchers believe bacteria make the tetrodotoxin, and the newts acquire it by eating those bacteria.1

Garter snakes are the most common predator, and some have developed resistance to the newt's toxin.1

Adults usually return to the same pool where they hatched to breed.1

Mito-hauslea

Mitoa: Newts do not make any sounds.

Egia: California newts make clicks, squeaks and whistles. Clicks are the most common, squeaks are used in defence, and whistles seem to be linked to recognising sex and to social rank.1
